Yongin City Replaces Water Purification Plant Disinfection with Eco-Friendly Equipment

Policy to Replace Yeomso with Sodium Hypochlorite
Completely Prevent Leakage Accidents During Container Transport and Replacement Process

Yongin City in Gyeonggi Province announced on the 24th that it plans to replace the disinfection equipment at the Yongin Water Purification Plant from the existing liquefied chlorine to sodium hypochlorite (NaOCl) to enhance the safety of the tap water supply process.

The city explained that this equipment replacement is based on the assessment that the existing liquefied chlorine disinfection equipment poses a risk of leakage accidents during container transport and replacement, which could harm workers or local residents.

The newly installed sodium hypochlorite system produces a hypochlorite solution by electrolyzing salt and disinfects tap water, and it is known to be safe enough to be widely used in places such as swimming pools.

The city plans to secure the budget through coordination with the city council and proceed with the equipment replacement.

The government is also strengthening regulations on liquefied chlorine. Since 2015, the government has classified liquefied chlorine as an accident-prone substance and has tightened regulations by requiring chemical substance statistical surveys, off-site impact assessments, hazardous substance management plans, and regular and ad hoc inspections.

Meanwhile, the Yongin Water Purification Plant, which began operation in 2002, currently supplies tap water to the Cheoin-gu area. Once the ongoing expansion construction is completed, it will be able to produce 200,000 tons of tap water per day starting next year and supply areas such as Dongbaek District and Cheongdeok District, which are currently supplied by the metropolitan waterworks.

Mayor Lee Sang-il said, "Introducing the sodium hypochlorite system will not only make the tap water supply safer but also improve the quality of the tap water."
